Web11 sept. 2016 · The multiplicative inverse or simply the inverse of a number n, denoted n^ (−1), in integer modulo base b, is a number that when multiplied by n is congruent to 1; that is, n × n^ (−1) ≡ 1 (mod b). For example, 5^ (−1) integer modulo 7 is 3 since (5 × 3) mod 7 = 15 mod 7 ≡ 1. The number 0 has no inverse. Not every number is invertible. Web12 dec. 2024 · The design of a lightweight, secure, non-linear 4 × 4 substitution box (S-box) suited to Internet of Things (IoT) applications is proposed in this work. The structure of the 4 × 4 S-box is devised in the finite fields GF (2 4) and GF ( (2 2) 2 ). The finite field S-box is realized by multiplicative inversion followed by an affine transformation.

Web9 apr. 2024 · The easiest trick to finding the multiplicative of any rational number (except zero) is just flipping the numerator and denominator. We can also find the multiplicative inverse by using a linear equation as follows. In the below equation y is the unknown multiplicative inverse. 8/9 * y = 1. y= 1/ (8/9) y=1* (9/8) y=9/8. Web10 aug. 2024 · The multiplicative inverse property of numbers states that when a number is multiplied by its multiplicative inverse, the product obtained is a multiplicative identity, i.e., 1. Mathematically it is represented as: For any number a, if a × b = 1, then b is the multiplicative inverse of a. For example, 15 × 1 15 = 1, therefore, 1 15 is ...
